| 中文摘要: |
| 西调钼矿位于华北板块北缘的法库断凸与吉黑褶皱系的接壤部位,该区具有良好的斑岩型钼矿的成矿潜力。西调钼矿主要产于石炭系黄顶子岩组及侵入的侏罗系晚期二长花岗岩之中,钼矿石呈细脉浸染状产出。激电中梯及钻探结果显示矿体主要受区域上北北东向构造控制,多呈近南北向展布,钼矿(化)体主要位于高阻的中心以及高极化率体边缘的位置。土壤地球化学测量圈定Mo、Au、Ag、Cu、Pb、Zn异常共计53处,其中以Mo的异常规模最大、强度最高,并且显示HT1、HT2、HT3等3个综合异常区带,HT1异常区带与发现的钼矿(化)体吻合度较高。文章在详细研究矿床地质特征、地球物理特征及地球化学特征的基础上,初步推断其成因类型为与燕山期花岗岩有关的斑岩型钼矿床。同时认为该区燕山期岩浆与石炭系黄顶子岩组的接触地带、高阻及高极化率以及土壤地球化学Mo异常区是该区重要的钼矿找矿地带。 |

| Xidiao molybdenum deposit is located at bordering area of Faku Faulted Convex on northern margin of North China platform and Jilin Heilongjiang fold system, which has a good metallogenic potential of Porphyry Molybdenum Deposit. Xidiao Molybdenum mine is mainly produced in Carboniferous Huangdingzi petrofabric and intruded adamellite of Late Jurassic, which was disseminated in veinlets. Induced electrical mid-gradient and drilling results show that the molybdenum orebodies are located at the center of the high-resistance center and the edge of the high-polarization, which are mostly distributed in the North-South direction and controlled by the NNE structure. Soil geochemical survey delineated 53 anomalies of Mo, Au, Ag, Cu, Pb and Zn, of which Mo has the largest anomaly and the highest intensity. The results also show three comprehensive anomaly zones of HT1, HT2 and HT3, of which HT1 is the highly consistent with the discovered molybdenum ore. Based on a detailed study of the geological, geophysical and geochemical characteristics of the deposit, it is preliminarily concluded that the genetic type is porphyry Mo deposits associated with the Yanshanian granite. It is also considered that the contact zone between Yanshanian magmatic rock and Carboniferous Huangdingzi formation, high resistance and polarization, the Mo anomaly area of soil geochemistry are important molybdenum ore-probing belts in this area. |
